try to change DRAW_HISTOGRAM by DRAW_LINE :IN SetIndexStyle( 0, DRAW_HISTOGRAM, DRAW_LINE, 1, BullBarColor );
 
How to named the line?
 

Hi guys.. I know this is an old thread, but i'm trying to get the line chart for overlay as I think that's the best way to view overlay charts.


I changed DRAW_HISTOGRAM to DRAWLINE but it now displays a lot many lines. Refer to the picture below.


Overlay Chart

I think this has to do because of these pieces of code (and possibly others too). Because this indicator was written for Candles, thus we have Bull/Bear and the two outlines. Can someone help to correct this please?

//+------------------------------------------------------------------+

   //Initialize Indexes
   Prefix = "OverLayChart" + SubSymbol;

   IndicatorShortName( "OverLay Chart( " + SubSymbol + " )" );

   SetIndexBuffer( 0, ExtMapBuffer1 );
   SetIndexBuffer( 1, ExtMapBuffer2 );
   SetIndexBuffer( 2, ExtMapBuffer3 );
   SetIndexBuffer( 3, ExtMapBuffer4 );

   SetIndexStyle( 0, DRAW_LINE, DRAW_LINE, 1, BullBarColor );
   SetIndexStyle( 1, DRAW_LINE, DRAW_LINE, 1, BearBarColor );
   SetIndexStyle ( 2, DRAW_LINE, DRAW_LINE, 1, BullBarColor );
   SetIndexStyle( 3, DRAW_LINE, DRAW_LINE, 1, BearBarColor );

   SetIndexEmptyValue( 0, 0.0 );
   SetIndexEmptyValue( 1, 0.0 );
   SetIndexEmptyValue( 2, 0.0 );
   SetIndexEmptyValue( 3, 0.0 );


   return( 0 );

The linechart is same as    simple moving average  period one  close price

So why not place that moving average on the chart with your candlestick ??? 

 

Hi guys,

i know that this topic is old, but as I don't achieved show the graphic in lines...

Anybody knows how convert the histogram to lines? I think that it can't be too difficult to someone that knows programe for MT4 but unfortunately I'm a beginner.

Thanks in advice if someone can help.

Cheers. 

 

There is someone who added the MA. The coder is LEGRUPO.

The modified Overlay charts indicator is included here.
